Maybe instead of adding mor #ifdef'ery here, we can turn lowlevel_init() into a "weak" function that can be redefined by board specific code?
The lowlevel_init() is an assembler function called from another assembler function and the attribute .weak doesn't work. There are no assembler file in the U-BOOT tree which use weak functions. Do you know how can I make an assembler function weak?
